9 Claims.

The present invention relates to windows and operating. mechanisms therefor and has particular relation to such mechanisms oi this kind operated by fluid pressure and other power devices.

Heretoi'ore window operators, used on motor vehicles, have comprised various power actuated devices including those utilizing suction available in the intake manifold 01' theengine or other sourceoi less-than-atmospheric pressure,

to raise and lower the windows, the devices being controlled by suitable means. In the case 01' suction operators, in order to prevent the unauthorized i'orcing opening of windows, means have been provided to prevent movement of the windows except under the influence of suction.

It is desirable not to apply such locking means to prevent movement in the opposite direction, since it may he wished to close a window at times when the fluid pressure differential or other source 01' power i not available, as for example it may be desired to close the window 01 an automobiie when the engine, depended upon as the source oi. power, is not running, and perhaps cannot be run by reason of some mechanical defact or the like. V

Ordinarily, however, the windows of a vehicle when fully opened are in the well of the door below or so close to the sill that they cannot be gripped with the finger so as to be raised manually.- It is an objective of the present invention to overcome this di'fliculty; to provide means for raising a window slightly, so that it may be engaged and raised by the hands at time when no power is available to raise the window.

These and other objects and advantages will appear from the following description of the typical embodimentoi the invention shown in the accompanying drawing, wherein:

Fig. 1 is a side elevation of the window, window actuator, and control therefor;

Fig. 2 is an elevation, partly in section, of the valve unit employed to control the actuator, with parts appearing in section; and,

Fig. 3 is a detail view of a valve actuating element.

As shown in Fig. 1 the window ii in fully opened position is in the window well formed by the inner and outer surfaces of the body or door and may have its upper edge even with or slightly below sill i2 on the bottom wall 01' the window opening. The actuating means maycomprise a cylinder i3 hinged at H to a stationary partoi the structure having the window opening, a piston l5 movable in the cylinder being eflective through piston rod it to swing bell crank lever i'l about the latters pivot Ill. The bell crank carries a roller i9 engaged in a track 2l secured to the lower edge of the window, so that upon counter-clockwise movement of the bell-crank (movement of piston to the'right) the window will be raised or closed. and upon subsequent clockwise movement of the bellcrank, the window will again be opened.

For operating the suction actuated device a pair of conduits 22 and 23 are extended from the ends of cylinder i3 to a, valve body 24 contain-.

ing valves which normally open communication between both conduits 22 and 23 and a conduit 25 which extends from the body to a source of suction, such as the intake manifold of an internal combustion engine. Each of the valves, which may be of any suitable type, such as'the construction shown in said application of Anton Rappl, Serial No. 383,176, may have a spring backed, manually depressible push button having a stem 23 provided with parts 23 for engaging the valve, the valves being sb arrangedthat depression of upper push button 26 ,may break prevent openingmovement of the window, i. e.,

movementmf the pistonto the left in Fig. 1, except when difierential pressures are acting upon opposite faces of the piston: suction from conduit 22 and atmospheric pressure from conduit 23. However, the piston may inthe absence of any pressure differential be moved by an extraneous force in the opposite direction, to the right in Fig. 1.

In order to bring the window partially out of the well and above sill l2 within the grasp of the hands so that it may be raised manually, a spring I is disposed between a'fixed abutment member 42 and head 43 of a rod 44, the latter in the illustrated embodiment being mounted for sliding movement in member 42 and valve body 24, and

the head 43 engaging an extension 45 of the bell crank I! under pressure of the spring. For preventing the spring II from always raising the window ii to the-broken line position in Fig. 1

. separate.

the broken line position of Fig. 1.

ever, the power unit I3, I is ineffective and it is when pressures on the opposite'faces of piston I5 are equalized, latch or clutch means are proby a cap 49 secured to the casing II. A part 5| having an inclined or cam face, 52 extendsfrom the actuator stem 28 of the"'up" button 2!, the inclined face being engageable with the end faces of blocks 48, to move the latter against the compression of spring 48, when the button is pressed.

In operation, when pressed, and the power unit l3, I5 is operative to swing lever II clockwise, lowering the window into the well, the latch mechanism just disassembled will not interfere with such action. This is for the reason that such action raises'rod 44, and any clutching of blocks 48 to the rod result in their release, since as they move upwardly the divergence of walls 41 allows them to Also when the up" button It is pressed and the power unit l3, I5 is operative to raise the window, the camil will be effective to release the clutch or latch blocks, so that the window may be raised to any desired degree by the cylinder and piston power means. The latch mechanism is effective when the window is in fully lowere position or nearly fully lowered position, and neither button is being pressed, to revent the spring ll from raising the window to when, howdesired to raise the window, pressing button 26 will result in release of the latch mechanism al.- lowing spring II to raise the window to a position partially out of the well and above the sill -so that it may be engaged by the hands and be moved manually to closed position or other raised position.

It will be understood that the window and operating mechanism may be of any suitable construction, including suitable counterbalancing means, if desired. The present invention provides spring means for initiating movement of th window from one terminal position, from opened position in the form shown, which may be especially advantageous in the case of a window that is not fully counterbalanced.

It will be understood further that the apparatus herein shown and described is merely illustrative of the inventive principles involved,-and that the same may be otherwise embodied without departing from the spirit of the invention or the scope of the appended claims,
